NMR and selective deuteration data indicated that the reaction of 1,3-butadiene with EtLi occurred as 1,4- and 1,2-addn. to the exclusion of 2,1-addn. The compn. of end groups of a product obtained at the starting of oligomerization differed significantly from that of a product obtained at the stage of chain termination by EtOH and depended only on the nature of the reactant (monomer or alc.). The compn. end groups formed during chain termination was independent of the length of the oligomer chain. During alcoholysis of oligobutadienyllithium, terminal vinyl groups were formed mainly from monolithium adducts.
